Description

What is the Difference of Polymex 7010-Pu Marine Glue Adhesive? Marine Marine Glue is a polyurethane-based and one-component adhesive that reacts with moisture in the air. The higher the humidity and temperature in the air, the faster the glue will dry. Polyurethane glue is widely used in the marine industry because it has a flexible structure and is very resistant to water. It is resistant to shaking and impacts due to its flexible structure. It does not open easily from the ground it adheres to and does not dissolve in water. It has a problem solving feature due to its certain heat resistance. Furniture, chipboard, wood and textile sector are the areas where marine glue is mostly used. Pu Marine Marine Glue Adhesive Adhesive Glue                                                                                                                             Marine Glue Adhesive For a good adhesion, the glue should form a structure that does not tear easily and is resistant to water and impacts. Of course, the application area of the glue is also very important. When the glue dries, it forms a film layer. The structural strength of the film is important in the quality of the glue. The fact that the glue adheres very well to the floor does not indicate that it is a good adhesive. Fast drying glues (popularly known as Japanese glue) adhere very well to the applied area. However, since the film it forms is not flexible and has high impact resistance, its usage areas are limited. The absence or very few air bubbles in the film structure formed by the adhesive glue increases the strength of the glue. Pu Marin Marine Glue Adhesive How Should Quality Glue Be?                                                                                                        Air bubbles in dried glue cause poor adhesion between surfaces. The quality of the adhesion will be reduced as there will be ruptures in the compartments where air bubbles are present. Therefore, a quality glue should not contain air bubbles when it dries. Where air bubbles are present, mechanical strength will be low. Therefore, tearing or ruptures will be too much. Pu Marin Marine Glue Adhesive One-component polyurethane Isocyanate groups in glues react with the humidity of the air and start to dry. During this reaction, carbon dioxide is released and air bubbles form in the adhesive layer. This reduces the bonding quality. A good single component polyurethane glue should have no (or very few) air bubbles, should not soften as the temperature increases, should be flexible and water resistant.
